Description

Gasoline composition and method for producing the same

The present invention relates to a gasoline composition using lignocellulosic biomass and a method for producing the same.

Biofuels are carbon neutral and are expected to be used to reduce greenhouse gas emissions.

In recent years when there is concern about the progress of environmental destruction, reduction of the environmental burden of gasoline for automobiles has become a social demand. As a method for meeting such social demands, attempts have been made to use bioethanol produced from corn, sugar cane and the like in the production of gasoline for automobiles.

Fuels produced from plants such as bioethanol, so-called biofuels, meet GHG (greenhouse gas) emission standards, but the plants that serve as the raw materials are limited. Currently, corn and sugarcane are the main raw materials, but since these plants are also edible, there is a concern that ethanol production may cause competition with food production.

Therefore, research is underway to produce biofuel that does not cause competition with food production. For example, Patent Document 1 proposes a method for producing ethanol from cellulose constituting non-food parts such as stems and leaves that are normally discarded. Non-Patent Document 1 describes a method for producing bioethanol.

JP 2008-182925 A

According to the method of producing biofuel using cellulose, it becomes possible to reduce the emission amount of carbon dioxide, which is GHG, without causing competition with food production. However, there is a problem that ethanol produced by this method is expensive.

In addition, ethanol is more reactive with metals than petroleum-derived gasoline bases, so if used in large quantities, it may corrode aluminum materials used in automobile fuel supply systems and cause fuel leakage. . Therefore, in Japan, the maximum amount is 3% and cannot be mixed in large quantities.

Therefore, the present invention provides a gasoline composition that uses lignocellulosic biomass, which is a plant-derived resource that does not compete with food production, and that satisfies the properties required for use in a gasoline engine, and a method for producing the same. For the purpose.

In order to achieve the above object, the present inventors have conducted intensive research, and as a result, have used penten produced from hemicellulose contained in lignocellulosic biomass to determine the properties required for the use of a gasoline engine. I found out that I can meet it. That is, the present invention is a gasoline composition containing 0.3 to 10.0 vol% of hemicellulose-derived pentene. The present invention is also a method for producing a gasoline composition comprising a step of mixing hemicellulose-derived pentene in an amount of 0.3 to 10.0 vol%.

<< Method for producing gasoline composition >>
The hemicellulose-derived pentene can be obtained, for example, by producing pentanol from hemicellulose contained in lignocellulosic biomass and dehydrating the produced hemicellulose-derived pentanol. From hemicellulose, pentanol is hydrolyzed, hydrolyzed, and hydrolyzed into hemicellulose in the aqueous phase in the presence of an Ir-Re (iridium-rhenium) catalyst and at a temperature at which hemicellulose is decomposed. By adding and dissolving an oil phase comprising pentanol, it is possible to efficiently obtain pentanol in a single reaction vessel (Japanese Patent Laid-Open No. 2016-33129).

The Ir—Re catalyst is not particularly limited on the basis of containing Ir and Re, but Ir—ReOx / SiO ₂ can increase the conversion of hemicellulose and the yield of pentanol. Here, x in ReOx represents an oxidation number and is an arbitrary real number. In particular, in the case of Ir—ReOx / SiO _2, it is preferable that the molar ratio of Re to Ir is 1 or more because pentanol can be obtained in a higher yield.

As the oil phase, for example, saturated hydrocarbons such as normal paraffin, isoparaffin, cycloparaffin, or aromatic hydrocarbons are preferable.

The oil phase does not inhibit the reaction in the hydrolysis step and hydrocracking step described above. For example, when ether is used as a solvent, the ether itself is decomposed, so that the function as an oil phase for dissolving alcohol can be impaired. Further, alcohol having an OH group or the like adsorbs to the catalyst and covers the active site, so that the catalytic ability may be impaired. In addition, unsaturated hydrocarbons, such as olefinic hydrocarbons, themselves are hydrogenated, consuming hydrogen used for hydrogenation of glucose and hydrocracking of sorbitol, reducing the yield of pentanol. . In addition, although aromatic hydrocarbons can also be hydrogenated, since the reaction rate of such hydrogenation is slow, it can also be used as a solvent.

The oil phase needs to be a liquid phase (liquid) at a temperature and pressure as reaction conditions for the Ir-Re catalyst. Typically, since the reaction conditions of the catalyst are 140 ° C. to 200 ° C. and 1 MPa to 10 MPa, the boiling point of the solvent is 140 ° C. or higher at 1 MPa, preferably 200 ° C. or higher at 1 MPa, more preferably 290 ° C. or higher. It is. Moreover, since it will become difficult to collect | recover alcohol if it will become a solid phase when taking out an oil phase, it is preferable to maintain a liquid phase also at normal temperature normal pressure. For example, n-dodecane or n-decane can be used as such a saturated hydrocarbon. In addition, you may use an oil phase in mixture of 2 or more types.

Other methods for producing pentanol from hemicellulose are described in, for example, Sibao Liu et al., “Green Chem.”, “2016”, “18”, “165-175”.

Pentanol can be converted to pentene by a dehydration reaction using a known acid catalyst. The obtained pentene contains 1-pentene and 2-pentene. Further, it may be fractionated into 1-pentene and 2-pentene by precision distillation.

Cellulose-derived hexene can be obtained, for example, by producing hexanol from cellulose contained in lignocellulosic biomass and dehydrating the produced cellulose-derived hexanol. Hexanol from cellulose is hydrolyzed and hydrolyzed by hydrolysis and saccharification of cellulose in the aqueous phase in the presence of an Ir-Re (iridium-rhenium) catalyst and at a temperature for decomposing cellulose. By adding and dissolving the oil phase, hexanol can be efficiently obtained in a single reaction vessel (Japanese Patent Laid-Open No. 2016-33129). As a catalyst and an oil phase, the thing similar to what was demonstrated by the manufacturing method of the above-mentioned hemicellulose origin pentene can be used. Other methods for producing hexanol from cellulose are described, for example, in Sibao Liu et al., ChemSusChem, 2015, 8 and 628-635. Hexanol can be converted to hexene by a dehydration reaction using a known acid catalyst. The resulting hexene includes 1-hexene, 2-hexene, and 3-hexene. Further, it may be fractionated into 1-hexene, 2-hexene and 3-hexene by precision distillation.

Hemicellulose-derived pentene and cellulose-derived hexene may be produced separately from lignocellulosic biomass in separate reaction vessels, and both hemicellulose-derived pentene and cellulose-derived hexene are obtained from lignocellulosic biomass in the same reaction vessel. It may be manufactured.

For example, the gasoline composition according to the present invention can be obtained by mixing the hemicellulose-derived pentene obtained as described above with a base gasoline base (hereinafter referred to as base gasoline). When mixing cellulose-derived hexene, cellulose-derived hexene obtained from lignocellulosic biomass in a reaction vessel different from hemicellulose-derived pentene may be mixed, or lignocellulose in the same reaction vessel as hemicellulose-derived pentene. The cellulose-derived hexene obtained from the biomass may be mixed together.

In order to obtain a gasoline composition having predetermined properties such as density as described above, the mixing amount of hemicellulose-derived pentene and the properties of base gasoline may be adjusted. However, if there is too much hemicellulose-derived pentene, the oxidative stability is deteriorated as described above, or the 50% distillation temperature is lowered and the fuel economy is sometimes deteriorated. The properties of the base gasoline can be adjusted by a known method.

The gasoline composition according to the present invention may be used as it is as a gasoline fuel, or may be used by further adding additives and other base materials.

Examples of additives include antioxidants such as phenols and amines, detergents such as polyisobutyleneamine compounds, metal deactivators such as amine carbonyl condensation compounds, and surface ignition inhibitors such as organophosphorus compounds, Examples thereof include antistatic agents such as anionic surfactants, cationic surfactants, and amphoteric surfactants, and colorants such as azo dyes.
